  7. Select the Create new bucket option.
  8. Select the require region.
  9. Select the Allow Immutability check box, then confirm the action in the dialog box.
  10. Click Save.
  11. Edit the backup plan that produced this error (code 2523) and specify for it the new backup destination created on steps 2-10.

In Backup for Windows

To do this, proceed as follows:

  1. In the application menu, select Edit Storage Accounts.
  2. Select the required AWS account, then click Edit.
  3. In the Bucket Name field of the Storage Account tab, select Create New Bucket.
  4. In the Create Bucket dialog box, specify the bucket name, then select the Enable Immutability** check box.

Note that you can only enable Immutability for new buckets. If you want to enable Immutability for an existing bucket, contact AWS Support
